Help with scaling please

@andy_8039 I've merged your three threads on this subject. Let's keep it all together or it just gets confusing for those trying to help you.

Have a read of Conrad's post further up this thread. Using the ruler with a custom measurement scale is the way to do this. By co-incidence I've just been doing something similar, matching custom logos to watch dials for mock up where the size needed to reflect exactly as the logo will appear on the dial. I knew both the size of the dial and the size of the logo so was able to set a custom measurement scale for each document, based on the dial diameter, showing how many pixels represented how many mm.  Then by using the measure tool, to drag out the known size of the logo, and then dragging guides to it, enabled me to position the logos exactly at the right size.

Hey Guys

I have realised my last post was a little confusing, my issue is really quite simple.

I am trying to create mockups of customers rooms so that i can show them different sizes of frames at scale.

having an image of their room with a sofa against the wall that is to have fames hung, i need to get the image to size so that the sofa matches the width of sofa measurement.

So i know the width of the sofa in cm but how to i get it to that size in the image so that i can add farmes to scale?

I am using an old version of Photoshop.

Thankyou

Andy

You don’t have to do much math if you use the command Image > Analysis > Set Measurement Scale > Custom to calibrate the Ruler tool to the known dimensions of that object in your photo like the sofa width. I did this to fit my mockup of specific frame sizes onto a photo of a wall at a site.

You mentioned that you’re using CS6. This feature might be available only in the CS6 Extended edition; because CS6 is now 13 years old I’m not exactly remembering if it’s in the standard edition.

Drag a guide to each edge of the known object. Use the Ruler Tool to measure the distance between guides. Divide the number of pixels by the known object size. That is your scaling factor.

Example:

Couch is 84" wide. Place a guide on each side in your image. Let's say its 420 pixels between guides. So scaling factor is 5.

Picture is 36" wide. 36 x 5 = 180. Scale picture to 180 pixels wide to match the couch. There will be some small parallax error (couch appears larger because its closer to the camera than the wall) but you can probably ignore that or scale the picture a bit smaller to compensate.

is this an indesign question?
